T0 all whom it may concern:

Be it known that I, J'ULIUs GRoETsoHEL, a subject of the German Emperor, residing at Plauen, in Vogtland, in the Kingdom of Saxony, Germany, have invented certain new and useful Improvements in Shuttle EmbroideringMachines, of which the following is a specification:

The subject matter of my invention consists of a shuttle embroidering machine, which differs from similar machines already known in that two rows of shuttles are adapted to be displaced vertically upward and downward, so that the needles are able alternately to coperate either with the one or with the other row of shuttles.

In the accompanying drawing a constructional form of the invention is shown by.

way of example.

Figure l is a vertical crosssection through the frame of the machine, viewed from the left side. Fig. 2 is a small portion of Fig. l shown on a larger scale. Fig. 3 is a rear view.

As shuttle embroidering machines in all parts and in all their diierent mechanisms are already thoroughly well-known as regards their method of operation, the drawing in this case merely shows essentially that which I consider to be my invention. In the drawing there are also shown some parts of the embroidery machine which are also already known, but this has been done merely with a view to assist in explaining the co-relationship existing between them and the frame. of the machine.

In the transverse wall (1*) of the machine frame there are arranged, on the front side of the machine, the iron beams (2, 3), while the iron beams (4, 5) are on the rear side of the machine. The parts (l) to (5) thus form the actual rigid vertical machine frame. The dotted line is intended to represent the embroidery-work which, as is well-known, is tightly stretched in a large square frame and, when it is desired to embroider further, it must be moved backward and forward in all directions in front of the needles (6, 7).

The novel feature which characterizes my invention is based upon the iact that two rows of shuttles are adapted to be moved vertically, by means of the rod (10), upward and downward opposite the row of needles (6). As shown in Fig. 2 the shuttles (8 and 9) coperate with the needles (6). In Fig. 1 the shuttles are shown in the elevated position, so that the row of shuttles (9) is opposite the row of needles (6). The same remarks apply in relation to the shuttles (8) and (9'), which are intended to work alternately with the row of needles (7 The shuttles move in the manner known along the shuttle races (1l, 12) and are moved to and fro in a horizontal direction by known actuating devices (13, la). The shuttle races (l1, 12) are fastened to the rod (10). This rod (10) is provided with teeth (l5) which engage with the teeth of the wheel l(16). I/Vhen, by the exertionof any force whatsoever, the shaft (17) is caused to rotate, then the rod (10) is caused to move vertically and then, whensoever it be necessary or when it be desirable, this movement will be brought into play in such away that first the row of shuttles (8), and then the other row `of shuttles (9), will alternately be causedto take up such an altitude that they will coperate, with the row of needles (6).

What I claim and desire to secure by Letters Patent, is:

l. In a shuttle embroidering machine a supporting frame, a rod mounted for vertical reciprocation in said frame, a plurality of rows of shuttle raceways iXed on said rod, shuttles mounted in each raceway, a row of needles and means for shifting said raceways whereby, when one raceway is `shifted into cooperative `relation with said row of needles another raceway is shifted into inoperative relation with said row of needles.

2. In a shuttle embroidering machine a to which the rows of shuttles alternatelyapopposite to which said rows of shuttles are pear for cooperation therewith. alternately moved by said rod, as specified. 10
